CLEAR ANSWERS TO COMMON QUESTIONS
Frequently Asked Questions

Any questions left?

What does this assessment measure?
It estimates which perception and information-processing channels are most active and which are less developed. Results describe the preferred ways of receiving and organizing signals from the environment.
How is the assessment completed?
It consists of short tasks and questions that compare different ways of perceiving and handling information. Select the option that best matches typical performance rather than an ideal response.
How long does it take and how many items are included?
Estimated completion time is about 11 minutes. The assessment includes 56 items.
How should responses be selected if more than one option seems accurate?
Choose the option that is most consistent across everyday situations. If unsure, select the first response that seems most typical.
How should the results be used?
Results can support learning planning, career guidance, team selection, and psychological consultation by clarifying dominant processing patterns. They are intended for practical interpretation and do not provide a medical diagnosis.
WHAT THE TEST MEASURES
About This Assessment
Diagnostic Methodology for the Structure of Signaling Systems Test

Assessment of the Structure of Signaling Systems Test

signal systemthinking style

This measure is designed to characterize individual differences in information processing and preferred sensory-perceptual channels. The Assessment of the Structure of Signaling Systems is administered as a brief set of structured tasks intended to support a clinically useful profile of relative strengths and weaknesses across signaling modalities. It was originally attributed to Donald O. Hebb.

The instrument contains 56 items and typically requires about 11 minutes to complete. Results are generally used to inform case formulation and to guide practical decisions (e.g., tailoring instruction, interventions, or workplace supports) by identifying which channels appear more engaged versus less engaged under test conditions. Interpretation should be integrated with other clinical data and contextual factors when using the Assessment of the Structure of Signaling Systems.
